With Apple doing really, really well, and with Microsoft having its first sets of negative figures since the company's founding, Microsoft CEO points his arrows towards Cupertino. In a talk to members of the press and analyst community, Ballmer talked about Microsoft vs. Apple.

I heard two versions of stories, or perhaps just different aspects of the same story.

1) MS has agreement with Apple to provide Office on Mac.
2) In MS, the Office team is the one possessing the most independency from the Windows team, because, as a killer application, it is mutual dependent between the OS and the Office, rather than the one-way dependent relied on by other products. So the Office team makes some independent decision not to put all eggs in the basket of Windows. Some rumor says SQL Server or other killer products may plan for the same.
